Hydronix RO-152-W14 Reverse Osmosis 6 Gallon (5.5 Draw-Down) Water Tank - White, 1/4" Port

This worked perfect

I have used a 5 gallon tank over the years, but find they only last about 3 years with the membrane leaking, and available water storage being limited. Like my 5 gallon tank after 3 years will only fill a cup around 36 ounces of water before the water starts coming out slowly. I'm guessing this smaller tank will do the same in a few years, but right now it's running at high pressure for at least 3-4 minutes before moderately slowing. Dealing with replacing a smaller tank is just more convenient, but you aren't going to notice a difference in the output between a large and smaller tank for most applications.

Pre pressurized. Works great. Smaller footprint

perfect replacement for my reverse osmosis water storage, plus stainless steel great price to and again faster delivery then estimated

There is not much about this. It fit where the old one was. It came charged with air pressure and works fine

No NSF/ANSI sticker or manufacturer date and serial on the tank. Tank is completely unmarked. Seems suspicious that this isn't meeting these health certifications.

Sturdy, strong design. This 5 gallon model works as a direct replacement for my 2.2 gallon tank that was almost 10 years old. I reused the valve from the old tank, if you don't have one, you will need to pick one up. It works in either the upright or horizontal orientation. I put 9 psi of pressure in the tank before I filled it. Working as designed.

Works great. Easy to install, works with great pressure.
